Inclusion Criteria:
- Patients, or their legal guardian, must give written informed consent prior to
initiation of therapy, and patients under age 18 must give assent in keeping with the
policies of the institution. Patients with a history of major psychiatric illness must
be judged able to fully understand the investigational nature of the study and the
risks associated with the therapy
- Patients with histologically confirmed FLHCC (or with documentation of original biopsy
for diagnosis is acceptable if tumor tissue is unavailable). The determination of
resectability status will ultimately lie in the clinical judgment of the surgical
oncologist and medical oncologist involved in the care of the patient. The definition
of resectability is as follows: hepatectomy can achieve a negative margin while
preserving more than 30% of the total estimated liver volume, sparing two contiguous
hepatic segments, and maintaining vascular inflow, vascular outflow, and biliary
drainage. Patients with extrahepatic disease are defined as having unresectable
disease
- Patient must have measurable disease defined as a lesion that can be accurately
measured in at least one dimension (longest diameter to be recorded) and measures >=
15 mm with conventional techniques or >= 10 mm with more sensitive techniques such as
magnetic resonance imaging (MRI) or spiral computed tomography (CT) scan
- Eastern Cooperative Oncology Group performance status (ECOG PS =< 1), or for patients
under age 18 Karnofsky performance status of >= 70
- No advanced cirrhosis, with Child-Pugh A
- Absolute neutrophil count (ANC) >= 1,000 /mm^3 (within 14 days of the first dose of
study drug)
- Platelets >= 100,000 /mm^3 (within 14 days of the first dose of study drug)
- Hemoglobin > 9.0 g/dL (may be transfused or receive epoetin alfa [e.g., Epogen] to
maintain or exceed this level) (within 14 days of the first dose of study drug)
- Total bilirubin =< 1.5 mg/dL (within 14 days of the first dose of study drug)
- Serum creatinine =< 1.5 times the upper limit of normal (ULN) or estimated creatinine
clearance (CrCL) > 40 mL/min (within 14 days of the first dose of study drug)
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])
and/or alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT])
=< 5 times institutional ULN (within 14 days of the first dose of study drug)
- Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy
test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin)
within 24 hours prior to the start of study drug
- Women must not be breastfeeding
- WOCBP must agree to follow instructions for method(s) of contraception from the time
of enrollment for the duration of treatment with study drug(s) plus 5 half-lives of
study drug(s) plus 30 days (duration of ovulatory cycle) for a total of 5 months post
treatment completion
- Men who are sexually active with WOCBP must agree to follow instructions for method(s)
of contraception for the duration of treatment with study drug(s) plus 5 half-lives of
study drug(s) plus 90 days (duration of sperm turnover) for a total of 7 months
post-treatment completion
- Azoospermic males and WOCBP who are continuously not heterosexually active are exempt
from contraceptive requirements. However, WOCBP must still undergo pregnancy testing
as described in these sections. Investigators shall counsel WOCBP and male subjects
who are sexually active with WOCBP on the importance of pregnancy prevention and the
implications of an unexpected pregnancy. Investigators shall advise WOCBP and male
subjects who are sexually active with WOCBP on the use of highly effective methods of
contraception, which have a failure rate of < 1% per year when used consistently and
correctly. At a minimum, subjects must agree to the use of two methods of
contraception, with one method being highly effective and the other method being
either highly effective or less effective as listed below:
- HIGHLY EFFECTIVE METHODS OF CONTRACEPTION:
- Male condoms with spermicide
- Hormonal methods of contraception including combined oral contraceptive
pills, vaginal ring, injectables, implants, and intrauterine devices such as
Mirena by WOCBP subject or male subject's WOCBP partner
- Nonhormonal intrauterine devices, such as ParaGard
- Tubal ligation
- Vasectomy
- Complete Abstinence
- Complete abstinence is defined as complete avoidance of heterosexual
intercourse and is an acceptable form of contraception for all study
drugs. Abstinence is only acceptable when this is in line with the
preferred and usual lifestyle of the subject. Periodic abstinence
(e.g., calendar, ovulation, symptothermal, profession of abstinence for
entry into a clinical trial, post-ovulation methods) and withdrawal are
not acceptable methods of contraception. Subjects who choose complete
abstinence are not required to use a second method of contraception,
but female subjects must continue to have pregnancy tests. Acceptable
alternate methods of highly effective contraception must be discussed
in the event that the subject chooses to forego complete abstinence
- LESS EFFECTIVE METHODS OF CONTRACEPTION:
- Diaphragm with spermicide
- Cervical cap with spermicide
- Vaginal sponge
- Male condom without spermicide
- Progestin-only pills by WOCBP subject or male subject's WOCBP partner
- Female condom
- A male and female condom must not be used together
Exclusion Criteria:
- Any other malignancy from which the patient has been disease-free for less than 2
years, except for non-melanoma skin cancer, or in situ carcinoma of any site
- Patients who have organ allografts
- Patients who have had a major surgical procedure, open biopsy, or significant

cycle 1 day 1 therapy after 24 hours from pre-treatment biopsy
- Autoimmune disease: patients with a history of inflammatory bowel disease (including
Crohn's disease and ulcerative colitis) are excluded from this study as are patients
with a history of autoimmune disease (e.g., rheumatoid arthritis, systemic progressive
sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g.,
Wegener's granulomatosis])
- Known history of testing positive for human immunodeficiency virus or known acquired
immunodeficiency syndrome

the administration of study drug hazardous or will obscure the interpretation of
adverse events (AEs), such as a condition associated with frequent diarrhea

gastrointestinal perforation, intra-abdominal abscess, gastrointestinal obstruction,
or abdominal carcinomatosis which are known risks factors for bowel perforation

tachycardia are eligible), or significant vascular disease or symptomatic peripheral
vascular disease
- Patients who have history of other diseases, metabolic dysfunction, physical
examination finding, or clinical laboratory finding giving reasonable suspicion of a
disease or condition that contraindicates the use of an investigational drug or that
might affect the interpretation of the results of the study or render the subject at
high risk from treatment complications
